A pe bellows

Abstract

The invention belongs to the technical field of pipelines, and is specifically a PE corrugated pipe; it includes a corrugated pipe body: a seepage hole is opened in the trough of the corrugated pipe body; Elastic corrugated membrane, a sliding cavity is formed between the elastic corrugated membrane and the guide tube; the outer wall of the elastic corrugated membrane is sleeved with a ring-shaped toggle column, and the upper end of the ring-shaped toggle column is connected to the top of the guide tube through an elastic pull piece ; An annular extrusion bag is sleeved between the inner bellows and the outer bellows, and a guide chute is provided on the outer wall of the inner bellows, and one end of the guide chute communicates with the annular extrusion bag, and the other end of the guide chute One end communicates with the diversion tube; an elastic push rod is slidingly inserted into the guide chute, and the end of the elastic push rod is connected to the outer wall of the ring-shaped toggle column; the granular soil or gravel washed by rainwater in the diversion tube is Under the action of extrusion and expansion, it is broken, and then the water flow is discharged through the seepage hole.

Description

technical field [0001] The invention belongs to the technical field of pipes, in particular to a PE corrugated pipe. Background technique [0002] The bellows is a cylindrical thin-walled corrugated shell with multiple transverse corrugations, which is elastic. Due to the geometrical characteristics of the bellows, the bellows are allowed to produce large deformation. Compared with smooth light pipes, in addition to sufficient strength, it also has greater flexibility and high fatigue resistance under cyclic stress. [0003] The single-wall corrugated pipe is a pipe with corrugated inner and outer surfaces, while the double-wall corrugated pipe is a pipe with a ring-shaped outer wall and a smooth inner wall. Corrugated pipes are mainly used for: urban drainage, sewage engineering, drainage engineering, farmland irrigation, sand control engineering, low-pressure water supply system, municipal drainage, renovation of sewage pipes, buried sheathing of wires and cables, etc. ...

AI Technical Summary

Problems solved by technology

[0004] When there is a lot of rain in the saline-alkaline desert area, it is easy to make the granular or massive soil or gravel under the expressway wash to the opening of the bellows, and then the granular soil or gravel will be blocked in the seepage hole, and the high-speed The road produces water accumulation; at the same time, the saline-alkali corrosive liquid mixed in the granular stone or gravel is easy to corrode the inner wall of the seepage hole, which will cause damage to the seepage hole, which will affect the diversion and drainage of the bellows
